摘要:
The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having an additive, such as an organic acid, an acidic or neutral salt or an organic acid in combination with an acidic salt or neutral salt added thereto.
摘要:
A paper wrapper for a cigarette is prepared using fine particle size calcium carbonate as the mineral filler for the purpose of burn rate, puff count and tar delivery control.
摘要:
This invention provides smoking compositions which contain a novel vanillin flavorant-release additive.A cigarette smoking product comprising (1) a combustible filler selected from natural tobacco, reconstituted tobacco and tobacco substitutes, and (2) a paper wrapper which has incorporated therein a flavorant-release additive corresponding to the formula: ##STR1## where R is methyl or ethyl.
摘要:
This invention provides polyheterocyclic compound useful as a flavorant additive.In one embodiment, this invention provides a polyheterocyclic flavorant additive for smoking compositions such as 1,2-bis(3,5,6-trimethyl-2-pyrazyl)ethane: ##STR1## Under smoking conditions the above illustrated polyheterocyclic additive flavors the mainstream and sidestream smoke.In another embodiment, this invention provides a polyheterocyclic such as 1-(3,5,6-trimethyl-2-pyrazyl)-2-(2-pyridyl)ethane.
摘要:
This invention provides foodstuffs which contain a substituted-heterocyclic compound as a flavorant additive.In one of its embodiments this invention provides food compositions which contain a substituted-pyrazine flavorant additive such as 2,3-dihydroxy-2,3-dimethyl-1,4-bis(3,5,6-trimethyl-2-pyrazinyl)butane: ##STR1## .
摘要:
A method is disclosed for preparing chiral nicotine and nicotine analogues of the formula: ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 are hydrogen or alkyl and R.sub.4 is alkyl. Also disclosed are novel intermediate compounds and a novel method for preparing 1-methylprolinol from prolinol, which compounds and method are useful for the preparation of these nicotinoids.
摘要:
This invention provides tobacco and non-tobacco smoking compositions which contain a pyrazine-containing polyheterocyclic compound as a flavorant additive.In one embodiment, this invention provides tobacco compositions which contain a polyheterocyclic flavorant additive such as 1,2-bis(3,5,6-trimethyl-2-pyrazyl)ethane: ##STR1## Under smoking conditions the above illustrated polyheterocyclic additive flavors the mainstream and sidestream smoke.In another embodiment, this invention provides foodstuffs which contain a polyheterocyclic flavorant additive such as 1-(3,5,6-trimethyl-2-pyrazyl)-2-(2-pyridyl)ethane.
摘要:

摘要:
The production of 2-cyano N-substituted heterocyclic compounds by a process which involves the reduction of N-substituted lactams followed by reaction of the intermediate product with cyanide is described. This process permits the production of many known and novel compounds.
